Melachim Bais 8:18 Meaning and Commentary

2 Kings 8:18

And he walked in the way of the king's of Israel, as did the
house of Ahab
Imitated them in idolatry:

for the daughter of Ahab was his wife;
whose name was Athaliah, ( 2 Kings 8:26 ) , and by her he was drawn into idolatrous practices; of such bad consequence are marriages with idolaters; it is very much that so good a king as Jehoshaphat his father was should contract such an affinity; he suffered for it in more instances than one:

and he did evil in the sight of the Lord;
was guilty of idolatry, than which nothing was more displeasing to the Lord; for he made high places, and compelled his subjects to commit idolatry, ( 2 Chronicles 21:11 ) .

Melachim Bais 8:18 In-Context

16 And in the fifth year of Yoram Ben Ach’av Melech Yisroel, Yehoshaphat being then Melech Yehudah, Yehoram Ben Yehoshafat Melech Yehudah began to reign as Melech.

17 Thirty and two years old was he when he began to reign as Melech; and he reigned as Melech shmoneh shanah in Yerushalayim.

18 And he walked in the derech malkhei Yisroel, as did the Bais Ach’av; for the Bat Ach’av was his isha; and he did rah (evil) before the eyes of Hashem.

19 Yet Hashem would not destroy Yehudah for the sake of Dovid His eved, in accordance with His promise to him to give a Ner (Lamp) for him and his banim kol hayamim.

20 In his yamim Edom pasha (rebelled) from under the yad Yehudah, and set a melech over themselves.
